After reviewing the steps I decided to follow this guy's advice and left the battery in.....one less item to possibly foul up. I don't know if it made it any faster (first time to open my phone, so nothing to compare it to) but I can say that my phone is charging for the first time in 6 months :D

I was paranoid about stripping the pentalobes - I used the ifixit pentalobe screwdriver TOGETHER with a layer of Glad Wrap (cling film or saran wrap for the non-Aussies) over the pentalobe holes - absolutely no problems. Guess it helps the driver head gain purchase?

After seeing the comments about trouble finding the carrier, I shut down the phone, did a soft reset (by holding the power and home buttons until it started and then shut down and stayed off), and removed the SIM. After the repair, I replaced the SIM and plugged it in to the charger. It started up and found the carrier (Verizon, as it happens) immediately. I would guess that only the soft reset made a difference, but I did both.

I pried one end of the back off only to find 2 funny little screws holding the other end on so I took my Dremel, like Jack said, and ground those suckers out. Once I had the back off I loosened all the screws then turned it upside down and shook the crap out of it. The screws went flying everywhere and fell on the floor. Its my moms house so of course she's got gross brown carpet. How am I supposed to find my screws in that? I get the vacuum out and go over every inch of the floor to suck up all them screws. Then I dump the bag on the table and all I find is a bunch of hair and gods knows what else, but no screws. When I look for my phone I see its covered in all that stuff that came out of the vacuum. I mean, what's up with that? How can I work on my phone if its covered in dirt? Nobody said anything about that, did they? The average guy's gonna screw up his phone big time if he follows these instructions and nobody warns him about all the dirt that's gonna end up in his phone. Are you kidding me!! Now what?

The physical battery replacement went off without a hitch, and saw that the phone had no network connection, but also had no way to unlock. The slide lock said "Slide for Emergency Call" over my custom wallpaper and sliding would give the passcode screen, but it would reject the 6 digit passcode (it would buzz and go dark after the 4th digit, re-awakening and putting in the last 2 would indicate bad passcode). Very frustrating! I get it into recovery mode and convinced iTunes to "update" the OS, but it still didn't let me in. I performed a restore to fully factory reset the phone, and it worked! Sort of... the start screen kept being replaced by "Temperature - phone needs to cool down" but it's cold. Temp sensor is on the battery and returning to old battery fixed it. New battery is bad, and phone is wiped. Fun night.

I'm going to guess that disabling the password might save you from a similar fate. So, I'll suggest BEFORE YOU START, backup your phone and disable the passcode. Good luck.

I didn’t find this particularly difficult, even though I’m pretty inexperienced at this sort of work. I watched the video overview to get me going and then followed the steps in the guide. My tips would be to keep the screws and parts organised as you dismantle, and ensure you read all the reassembly tips as you go; it’s easy to skip over them. I also found using the Liberty Kit to replace the pentalobe screws was worthwhile.

I didn't see any extra screws holding the back in place. I had to use the included pry tool to get the back off. Just start at the bottom and pry gently...if you just "pull" like the guide says it won't work.

Those little screwdrivers are easy to mix up, for those of us without ultra-perfect vision! Once I used the correct screwdriver, and my 13yo son's little fingers and perfect eyes, it went smoothly! Also my son noticed that the rubber piece around the camera len was covering the camera; it likely slid out of place when sliding off the back cover. A little playing around (with plastic tools only!) and it looks perfect now!

The replacement panel I got had two sheets of protective plastic on the inside and one on the outside. I used a toothpick to carefully lift and peel the two inside sheets off. One small one was over the lens on the inside. The other was over some large brown sheet of unknown function (though I think it goes over the battery). When I peel that away, some of the brown material tried to lift of with it, so be very careful.

From this point go to step ?? Just peel off the tape from the chip. Take some aluminium foil and cut a hole the size of the chip (Use a second layer of foil if you don't thrust it). Heat the chip as described at temperature 300 deg C for 5 minutes. Let it cool down. Reassemble and ..... hura WIFI is on again.

On my phone at least, there is a small gold and black part held down under the top screw. It goes black side up with the pressure contact touching the back of the phone when the cover is in place. Keep an eye out for correct orientation as you dismantle.

While the text refers to the pressure contact, the pictures do not show it clearly. The closet one that does has the yellow circle covering much of it. I was not sure if it was under or on top of the cover when re-installing. It's under.

The bottom screw on my phone was locked with some thread adhesive, and required more force to loosen it than I expected.

Even after removing the screws, the battery connector was rather firmly seated, and required a fair bit of persistent gentle prying with the opening tool before it came loose.

The ground clip came loose and nearly flew off while loosening the connector, so it would really help people if there were a warning on this step to watch out for the ground clip and make sure it doesn't bounce away.

The battery connector is attached to the battery. You're not going to completely lift it out and remove it. It pulls out from the socket you can see in step 5 picture 3. The pressure contact (little black and gold thing) will probably just slide out from under the connector. Not a problem.

The iFixit screwdriver that is recommended and provided will strip the screws here. HOLD OFF. I bought a ph000 screwdriver off the internet. Worked fine. Don't be tempted to proceed with the ph00 from iFixit. IT WILL STRIP!!

I completed this successfully, but this step gave me the most trouble. The pressure contact is really difficult to reseat. So much so that it should probably be called out more clearly in it's own step.

Top screw didn’t move with iFixit Philips #000 driver. The metal is too soft and in the result the screw was damaged while still in place. Having nothing to lose I also tried #00 and #0. Any way to remove the stuck screw? I would gladly saw it off if I could.

The Liberation Kit Philips head screwdriver strips the battery connector screws! It stripped the ne 1.7 mm Phillips screw circled in red in the photo above. I was able to remove the other screw, then I lifted the battery connector off while the red screw was still in position and wound the connector around in circles while lifting upwards and managed to unscrew the stripped screw. Advice, find a decent philips heard screwdriver for the internal screws like the two found on the battery connector.

Bottom screw was totally stuck, nothing could budge it. I removed top screw, heated up battery with hair dryer to release the glue, pulled it out using the spudger. Lifted up the metal plate thing (after taking out the ground piece and putting it aside). Cut off the flexible bit between the plate and the battery and twisted the plate around the screw as you did.

Well, the screw eventually came out—but only the top half! Yes, it split in two. Then the bottom half came out, still attached to the thing it was screwed in to (a sort of barrel).

I put the new battery in, put the bottom half (with the barrel) of lower screw back in its original position, replaced the ground piece and positioned the new plate over it, and screwed the top screw back in. Then put the top half of the lower screw in and tightened it.

Et voila!

Extra: It was helpful to discover that the 1.5 and 1.7 mm measurements refer to length of screw, not size of Phillips head.

When reassembling, use EST tweezers to get align the pressure contact over the top screw hole. using the pointy end of a spudger to assist: put the point through top screw-hole on the battery connector, then through the pressure contact and into the screw-hole. this will help to keep the small piece in place while re-seating the battery connector. Leave the top hole spiked as such until the screw in the bottom hole is gently fastened. Remove the spudger and replace the top screw.

Pressure contact needs to be remain EXACTLY in the same position if you remove/replace battery. I had to re-open my iPhone 4S after a battery replacement (the mobile connectivity was lost) and tweak the position of the Pressure to restore functionality.

Hi, I have a problem with that small piece which connect gsm antenna with the back cover. I missed that part and have a weak signal gsm, so I buy it and now when I put it there the Iphone wont turn on when the back cover is puted on. I know that somewhere is short-circuit but dont know how to solve it. Sorry for my english.

I used my 16x magnifier loupe to be certain I had the pressure sensor aligned with the screw hole - no problem, no stripping. I consider it indispensable for tricky steps like this, and IFixit sells a similar tool for just $14.

The pressure connector is the battery connector under the silver plate. BE CAREFUL. It seems like it'd be really easy to tear that pressure connector out without meaning to. The bronze and black thing is the ground, *not* the pressure connector. If you remove it just keep track of it and re-install it.

The phillips head screwdriver provided in the ifixit repair kit does not work well this these two screws after my first attempt at unscrewing the screws became stripped. The 1.7 mm phillips screw gave me the most trouble. It took an hour to unscrew after the screwdriver from the kit stripped the screw. I used a piece of masking tape over the screw for grip to loosen it, then used finger nail clippers as pliers to unscrew. I would recommend investing in a better screwdriver for this one step. Assembly is otherwise simple and easy.

Here's a tip if you're having trouble removing the 1.7 mm screw. I had real problems removing it – the 1.5 mm screw came out easily using a Phillips #000 screwdriver but I almost stripped the 1.7 mm screw using the same screwdriver. What I did instead was use a flathead screwdriver from the iFixit pro tech toolkit I got, the one with a "–" sign and 1.0 size. That worked perfectly!

There's only one Philips screwdriver with the kit but it failed to unscrew the top 1.7mm one off the connector unfortunately. Is the kit supposed to come with both the 1.7 and 1.5mm Philips screwdrivers?

I would agree that a decent magnifier would help as the screws and components are small.

Also take necessary precautions to ensure the screws are not lost or mixed up.

Other than being a bit fiddly (particularly the earth connector), the only challenge I had not covered was that the battery was fixed with glue close to where the connector is and despite releasing the battery along the side, I couldn't get the battery to lift out using the tab. In the end I had to use the plastic tools to gently lever the battery away, working from the outside edge and ensuring I wasn't levering against the volume control buttons.

The new battery is in and following the advise given, I hard reset the phone and all my usual functions are now running... and if this £18:00 fix gives the phone another year or two of use, it will be well worth the effort.

When i replaced my battery then my i phone4s suddenly diseabled to 4million hours or sonething big like that....So at the end i had to go for a flash..when it was updating in the middle there has been a error so my logo comes CONNECT TO ITUNES...so what can i do guzs????

The little contact thing that sits under top screw is always the biggest hassle to fit back into place (I do it after attaching the battery cable) with tweezers from ifixit.

My personal tips:

- plan that the incredibly tiny screws or the top-screw contact thing, might get away from you. so work in a space where you can find them easily. Not over carpet, etc.

- I use strips of tape on a piece of paper to secure the screws while they are out, and position them so I know which one goes on top of battery connector, and the one on bottom.

- If you have access to a spouse's/mate's iphone, in Accessibility settings there's a Magnifier option (triple-click home button) which does an amazing job at magnifying stuff at a circa 4-6" distance. Lacking any good magnifying glasses, this feature helped a lot. https://www.imore.com/how-use-magnifier-...

This picture needs to be greatly enlarged! The pressure plate sits directly underneath the battery connector, but cannot be seen here. It is also flat but about half the size of the battery connector, so you won't know you've ripped it up until you have! Picture two slices of bread but not the same size, stuck together.

No idea what exactly this step means. I just pulled the battery connector without trying to move the pressure contact. Installed new battery, plugged in connector and aligned the pressure contact slightly for the screw to fit.

Got a big scare as the phone would not connect to the cell network at first boot, only WiFi. Shut it off and when it rebooted it seemed to work. WIll probably know in a day or so if everything works fine or if there are interference issues, etc.

After reassembling the iPhone I the GSM connection wasn't working. After cleaning all parts with isopropyl alcohol it still didn't work. What solved my problem was to turn on WiFi and then synchronizing the date and time which was set to 1970-01-01. After a reboot everything worked just fine. :)

The black ground contact needs still more "flagging." This is a simple metal strip that is attached ONLY by the 1.5mm (upper) screw. It will help if you look at it before you remove the upper screw. Notice the gold contact arm and point. That contact point must be in a plane above every other surface inside the device when you replace the battery connector, because it makes a ground contact with the metallic inner surface of the device back plate.

When I replaced it, I used the Pentalobe driver to line up battery connector and ground contact with the screw socket post. I then attached the 1.7mm (lower) screw loosely, removed the Pentalobe driver gently, and inserted the 1.5mm (upper) screw into the assembly. There is a tab on the ground contact that helps it align properly once pressure begins to applied. I completed driving the upper screw, pressing lightly with the spudger on the battery connector plate to make sure it was seated on the pressure contacts. Finally, I completed driving the lower screw.

Wish the instructions had the warnings about the pressure contact before getting started. I removed it from the logic board because the warning was after the instructions. I managed to get it back in place and reassemble the phone. Nothing happened when I turned it on. Here I wrongly assumed the battery came pre-charged but it wasn't. I decided to plug it in to recharge it and was elated to see the empty battery symbol. I'm sending this from the phone!

I didn't find any need to remove the pressure contact. I just pried the battery connector up (gently) with a spudger and left the pressure contact in place. Connected the new battery and aligned the pressure contact screw hole. Replaced the screws, finished reassembly and all was good.

After reassembly, the CELL CONNECTION WASN'T WORKING. You might need to slightly bend the contact in step 5 up just a little, so it will make contact with the metal back plate. Did that and it worked perfectly.

putting them "on" something will just cause heartache and and an infected bladder...

°¿°

after a lot of froofroo and very errant iphone behaviour problems, i concluded that that tiny grounding piece must be being lazy as hello. i spread it out a bit to ensure a better contact with the back plate and everything appears to be working smoothly.

Just went through the replacement and the battery "plug" (step 5) on my replacement battery was slightly misaligned relative to the metal plate used to screw it onto the board. The plastic and "gold" "plug" was slightly askew on the metal plate, which meant that when the plug was inserted, the screw holes (step 4) were poorly aligned.

I managed to pull everything back into line using the screws, but the QC on these replacement batteries is a bit suspect.

Guess what happens when you rotate that ground connector 180 degrees...it grounds what I deduced to be the heat sink of the power amplifier for the speaker! So it is silent. It took me a couple of attempts to discover this as I was distracted by the new speaker not sitting down properly and a little dot of stuff under the main connector stuck to the pins. The latter was cleaned-off with a pin under 5x magnification followed by some isopropyl alcohol.

I suggest that Step 5 is more explicit about the orientation of this ground connector. It's only obvious after a really close look and if one has a lot to do like I did, it's a long time before one comes back to this step so the correct orientation is not obvious.

If you magnify picture 4 or picture 5 twice, you can view the ground clip under the blue tool. You need to reinstall the ground clip with the copper color prong facing "up." I believe the ground clip is what many are calling the "pressure contact point" because the copper prong of the ground clip does indeed have pressure asserted to it when it contacts the back cover of the iPhone 4s.

The hole in the pressure contact aligns with the top screw. The IFIXIT tool kit I bought contained a black sharp “thing” that I used to align the pressure contact with the top screw hole. I used this tool to align the bottom screw hole also. I put the bottom screw in first but did not tighten it all the way. A good magnifying glass with a light helped a lot. Tim

Aligning with the black pointy “thing” definitely helps. Also, the small copper end of the contact piece is supposed to stick up once attached, to make contact with the back plate of the phone after re-assembly. The piece slides under the silver metal plate, and the the pointer can be used to align the silver plate hole and the black/copper plate hole in place for the screw.

Yes, there did seem to be a lot of glue holding my battery in. At first I was afraid of breaking it, but after reading up on the subject I've learned that it is okay if the battery gets a little deformed. Due to the nature of the battery it will still work if slightly deformed.

I found the plastic pull tab to be useless. Peeled pretty much the whole battery out from the left side. Used a probe to "break" a few strands of glue to help. Just watch the connector and ribbon cable in the lower left corner as you pry up so you don't crimp them or damage them.

Tom you have never been so wrong. Removing the battery is the FIRST step ANYONE should do before repairing or attempting repairs on their phone. The iPhone has many different grounding points in the phone and having electrical current running to it poses a massive risk, especially with ESD (ElectroStatic Discharge). People, PLEASE make sure you remove your phone's battery FIRST before doing any repairs. Use a plastic, not metal, spudger, after unhooking the battery from the logic board, place the spudger along the right side of the battery NOT under the volume buttons, about an inch and a half lower (two roughly if a sim card is present) and start prying it up using the frame as the fulcrum, as you start to lift the battery from the adhesive make sure you slide the spudger farther under to get even contact so you do not damage the battery.

Try a used plastic credit/gift card to apply gentle pressure to lift the battery out of the phone, the short edge of the card fits within the gap on the logic board side between the battery and video cables. You can also use it on the opposite side if there is room between the battery and iPhone frame. This has worked on all of the 4 and 4s models I've replaced screens on.

Hello! My clients iphone 4s:n battery connector broke, when i tried accidentally take the battery out with a plastic tool from the wrong side.

Connector detached completely, so that the two middle ironcensors came with it and was stuck to the connector. When i screw the whole connector back to phone, it works with battery power, but the batterys downloading doesnt work. Are these two middle censors that are stuck in the connector exactly the ones that should be charging the battery? Do you know how i can fix this? I have already bought electrical conductor glue, but should the parts be cleaned somehow first? And how can i fix it, when the center metal sensors on the system board is also attached to the battery?

How can i clean out thiskind of part with windex? I have purchased almost all of the possible tools from iFixit and the electrical conductor glue i bought somewhere else. (http://www.ebay.com/itm/300915727408?ssP...)

i also skipped the battery removal step. the battery didn't get in the way, but it did make it difficult to see if the wifi grounding fingers (step 14) were underneath the case lip. everything worked in the end though so i don't think removing the battery is a strict requirement.

Please, Please, PLEASE avoid using probing elements to try remove batteries. I have had dozens handed in to me with punctures and two that actually started smoking due to people trying to prise the battery out. DO NOT DO IT.

The best way I have found to remove the battery is this process;

1) Try remove it with the pull tab directly, some will come out, some will not. Do NOT use excessive pull force else it'll deform the battery and reduce the capacity.

2) If the pull test didn't work, then get a hot air gun on medium and warm up the area around the battery for about 30 seconds, focusing on the perimeter of the battery. If you see ANY popcorn'ing then you're too hot, you don't want to cook the battery.

2.1) Wait about 30 seconds for the heat to now wick underneath the battery to soften the adhesive.

2.2) Now try pull the battery up, the extra heat should have softened the glue that you can remove the battery without excessive force and without sticking objects under the battery.

Be VERY careful NOT to pull off the part of the connector that is on the logic board! Mine now has only contact but no solder until I can get a small enough soldering iron and a less shaky pair of hands!

I lost the 1.5mm and 1.7mm screws when replacing my 4s battery. Is there a place that sells just these two screws? I bought a 4s screw kit from Zeeton.com but figuring out which screw out the of 39 screws were the the 1.5mm and 1.7mm was impossible.

Was having a hard time getting the screws back into the battery connector. Read another tip online that helped - pushed the end of my phillips screwdriver into some soft candle wax which gave it just enough stickyness to have the screw stay attached to the screwdriver while I was moving it toward the hole. Thought I'd pass that along.

I did as wazzamagu did (and stated above), "My Pentalobe tool was slightly magnetized so I used that to bring the screws in for tightening with the Philips screwdriver." That made replacing the screws fairly easy. Thanks for all the advice on this page. It was not hard at all. Go slow and carefully, everything is smaller in there than I expected. The "searching" thing came up as it seems for most people, but just took a reboot and all is fine.

Took about 15 minutes. The only thing that was confusing was the reference to parts, using the partname, and I didn't know what they were referring to. So I had to figure it out by the photos. Slightly frustrating. Got it in and it worked. My problem then, was it kept SEARCHING and couldn't find my carrier. I followed everyones advice on here, plugged phone into my computer to itunes. then turned off network settings in settings, then turned them back on, and I got 3 bars. good to go.

For the past couple of months, my phone had been dying very fast. I knew that my phone's battery capacity was getting quite low as this phone is older now, and is out of warranty. So I ordered a replacement battery about a week ago, and just installed it yesterday. The install was pretty easy, if you pay attention to where everything belongs. But my draining issue has not gone away. It stays charged a bit longer, my capacity is at almost 100%, yet it can't even hold a charge over night. I'm not sure what is causing this and would love any tips or stories from someone else!! Please help!!

OMG thank you iFIXIT, the apple store wanted 3 times the cost of this repair kit. It took less than 5 minutes with most of the time spent trying to prise out the battery as it was glued in nice and tight but steady pressure from the spudger did the trick.

I think the best advice would be to touch nothing with your fingers as with careful use of the spudger I was able to position the tensioner point no problem. Everything else was nice 'n' easy.

Finally there was no cell connection only Wifi when I powered up so I simply powered down and up again and all is well in the world!

The battery was incredibly hard to remove. I slid the spudger underneath the battery from the right side as far as it would go. Then, I worked it from the bottom to the top. The battery still was adhered and wouldn't budge using the pull tab. I wound up leaving the spudger underneath the battery at the top and then pressing down on the bottom of the battery to get leverage. After a few strong pushes, and then swapping the top and bottom in the last sentence, the old battery came loose.

I used tweezers to hold the tiny screws and align them with the screwdriver head before taking the screw to the destination hole.

One more tip.. if you don't have any other cartons or containers convenient, use the box that the product comes in as a workspace for holding the tiny screws while you work.

Be VERY careful not to pull on the plastic tab before you fully detach the adhesive or else you will rip the tab clean off. If you did this it is still possible to remove the battery. I just used the guitar pick tool things to slowly work it through the adhesive and under the battery

This is due to the date and time being set back to default. To fix this you will need to synchronize the date and time back to what it is currently.

You can do this by either:

- Connecting the phone to either a Wi-Fi network, Cellular Network (Mobile Data).

- Connecting the phone to iTunes (It will synchronize the time automatically once iTunes is opened and can detect and access the iPhone).

Once the date and time is synced you will need to turn airplane mode off and one as it may display 'Searching... 3G' or if it still says searching (which most of the time happens if the sim card has a sim pin lock enabled on it) you will then need to turn the phone off and on.

One thing I noted with the replacement battery - from AussieBattery here in Australia; not from iFixit - but the same problem might occur; is that the cable on the new battery had to be 'tamed' (bent here & there like on the old battery, before I could reseat the screws and even the battery itself. One again the black - pointy & flat ended - spudgers, that we use in desktop iMacs, were helpful in getting under that battery and releasing it from sticky-!&&*! I used a pair of '2.5' reading glasses for this job, but '3.0' might have been better, as those screws are INFINITESIMALLY small!!!!! :(

Thank you IFIXIT! The battery replacement went very well for me. I was exceedingly careful with the minuscule fasteners. Reading through the instructions, watching the video and reading these comments before jumping in helped. I found the parts and tools to be of good quality. I feel like I beat the system! I used a pair of diopter 3 reading glasses which was a real aid. I hope my comment encourages others...

My rare earth magnets came in handy when I managed to lose the little grounding connecter screws. Those little guys will go flying if, while trying to align them for reassembly, pressure gets applied in just the wrong way. I say one fly out and bounce off my shirt, then it was gone, on the floor I presume. I grabbed my stack of 8 little magnets, waved it around on the floor under where I was sitting and what do you know? A little screw was stuck to it! I never would've found it just by looking...

You really need to include information about the pressure sensor. It WILL inevitably pop out, leaving us wondering how and in what order it should be replaced. I had to look elsewhere for videos outside of iFixit to figure this out. Also, tell us which screwdriver to use using the label on the bit (PH000, P2, Y000, etc.). Providing only the sizes of the screws does nothing to help determine the appropriate bit to use when they aren’t labeled as such. Otherwise thank you!

I replaced the battery and the phone started right up. But I cannot get it to charge It was half charged when it went in new and I plugged it into a charger Checked it later - not charged. So tried another charger and the green charging light still will not come on . Any suggestions? Thanks Don

My iPhone 4s somehow has another connector on the battery. I cant connect the new battery to the phone. Its a complete different looking connector. And yes its never been replaced before or opened. The iPhone is one of the first versions for the german market after the fall of the simlock. Pls help

Was trying to fix guide but accidently messed some things up in formatting and I too also believe the picture is incorrectly displaying the 1.5mm(which is the left screw) and the 1.2mm(which is the right screw.

Organizer: tape cheap duct tape tacky side up to a tray. Get a ball point or roller ball pen. For every screw, write step number and a letter for color (R, O, Y, etc.) then stick the screw there. I bumped the table and nothing moved. Also use a big white towel as a work surface: nothing bounces away if you drop it. This helped re-assembly

My gold adhesive has torn, exposing a sliver of the flat wire beneath it. I have put a bit of insulation tape to prevent any contact between the wire and the top of the vibrator and metal piece on the logic board. I don't know if this is sensible or not. Depends whether the gold adhesive is intended to be an electrical contact with these bits, or an insulator from these bits! I will post to update once the phone is powered up / blown up!

Ok, I did all the steps and phone seems to be OK, wifi is actually working again, yaaay.

But cellular connection is messed up. It will have full reception (5 pins) for about 10 seconds, then drop to 1 pin for a couple seconds, then go into "searching" mode. After a few seconds in "searching" mode it will go back to full reception and the process repeats itself in a timely fashion, over and over again. Obviously I messed up somewhere but where? Which connections are faulty/beyond repair?

I dismantled the phone again and concluded that the digitizer cable was kind of loose (don't know if that affected anything, but i put it down firmly this time). I had 2 problems, the cellular connection I mentioned plus the phone would charge to 3 percent, die, and then repeat the procedure. What I did was I took out the battery, the tin plate above the cables, and lifted the dock connector. So I did not redo that much. I cleaned all contact surfaces as I had been told but chose to not do before.... I also took out the grounding clip by the battery connectors and bent it upwards quite a bit while also peeling away 2 mm of the black insulation material on the back of the phone to make sure the grounding clip connects well to the back of the phone. I also cleaned that surface with window cleaner, which is basically isoprypol alcohol as has been recommended. The cellular antenna connector I pushed down firmly to make sure it was connected, I was gentler the first time, now everything works.

On reassembly, note that the metal lip below the (red) 2.7mm screw and to the right of the (green) 1.2mm screw goes between the ribbon cable and the main logic board, as can be seen in the picture for Step 12. If you don't get this right, the 2.7mm screw is difficult and, worse, there's a risk the edge of the lip will tear the ribbon cable.

I had challenges here. As noted, the metal lip below the (red) 2.7mm screw and to the right of the (green) 1.2mm screw goes between the ribbon cable and the main logic board. That lip points away from you, towards the screen, THEN BENDS UP towards the power button. You need to pull the metal shield down a little (which stresses the ribbon cable) to get the hook-shaped feature free.

Got to step 13 and could not remove the 1.3mm screw (yellow circle), even using a different Phillips head screwdriver than the one that came with the kit. So frustrating. Was able to remove the other screws leading up to this point without difficulty (used the saran wrap trick on the other screws to prevent stripping, but this 1.3mm screw just would not budge).

Ended up abandoning the screen replacement--luckily the phone works after putting it back together.

In my case, the 1.3 screw (yellow) wouldn't tighten on reassembly. I might have tightened too much so that it stripped the screw hole. Anyone know whether this has damaged the board in some way. The phone works fine, but concerned about the long run.

If you just very slightly twist this plate clockwise as you are lifting it out, it will help as there is a little hooked piece at the lower edge on the very far right. You have to be careful not to turn it too much though because this hooked piece is right beside a ribbon that could be damaged.

If turn the plate clockwise doesn't do the trick, the hooked piece on the lower right comes off when you pull the plate towards you a tiny bit. Still, watch out not breaking that ribbon the hooked piece is behind of.

If you're having trouble removing the EMF shield, try using a plastic prying tool to lift the top right part while pushing it ever so slightly downwards with a finger. Consult this video for details: https://youtu.be/8fujLMaxJsw?t=6m42s

I've got a trouble at this step. Is there anybody who could help me out with my problem? When I was removing the camera module, accidently removed small element, which is marked with the red line http://i63.fastpic.ru/big/2014/1022/4e/9...

As I figured out - that is the SMD capacitor. After that Iphone was switched on, and it seems to be working fine at the moment, but I am very scared, if it will continue to work well without that small piece. Anybody to help?

In my case, the grounding clip was taped to the camera! In addition, my repair process stopped at this step as the left screw on the power button had come out and was floating around next to the camera slightly stuck to the tape. This was lucky since a loose screw in an iPhone under the logic board would be a bad omen.

I agree that the SIM card should be removed before you even start. After I completed this repair (waiting until this step to remove the SIM), the SIM card and holders won't go flush with the side of the phone anymore. The phone still works and everything else is fine, it's just annoying that I have a SIM holder sticking out about 1mm. I'm not certain this step caused this, but I'm just letting folks know that I agree with jmaelzer.

While "This may require a significant amount of force." may vary by individual device, I found it to be true. I used a straightened paper clip held with a (really good) pair of needle nose pliers and pushed straight in until it fully popped out.

That may depend on the specific device; significant force *was* needed to eject it in the case of the phone I'm working on. Putting it back in, however, was very easy and didn't require any significant effort.

Is there any reason why you still have the ribbon cable under the little metalic plate (right under the sticker that says "Authorized Service Provider Only") plugged in in STEP 10. And it is without any instruction step removed in STEP 12? I mean it's not like it is complicated, but when I got to that part I was confused there for a minute that I forgot some step, and then reassured myself that I did everything as it said in the manual.

I have done everything correctly but when i turn the phone on all i get is a blank screen. The phone operates as normal i.e. it rings, vibrates etc but the screen is just blank so you can't actually do anything with it :(

FWIW, I found it easier to replace during re-assembly by turning the phone front-side up, as on the Sprint-locked one I was working on, the SIM card faces that way. Otherwise, it tends to fall out (down) while trying to re-insert it if the phone is face down.

There is an additional cable that you have to disconnect that's under the headphone jack cable. You have to do this before you try to remove the logic board. Otherwise, you'll rip that cable.. and I just freaking did.

That power cable connector is very delicate. I managed to tear it just a tiny bit in the curve of the cable too. So I’ve got another part on order now. Apart from that the screen replacement went great ;) I’m not sure at which step the tear actually happened, it might have been during re-assembly when I was trying to get all these cables to stay on top of rather than go behind the motherboard. Realizing how easy that is to tear and keeping that in mind as you do this is important.

Not all screwdrivers are equal. I took mine in the shop and ground the blade thinner then made sure the end was square and flat. You can do this with an emery board or sand paper. You want a good fit in the stand-offs.

Ok so no fret here if you accidentally pull off the metal insert placed on top of the actual antenna. This step needs to be rewritten imo, the deal here is that there is an actual 'socket' looking deal underneath here that you need to lift up. There is a metal tab semi'glued' to that part of the antenna and it does come off easily, however all you need to do is press them back together to get them back, I believe it to be a range 'extender' of sorts.

So your looking to actually lift up what looks a lot like a ribbon cable as well in this step. YOU SHOULD NOT HAVE A PIECE REMOVED IN THIS STEP, it's still in the case at this point.

When reassembly - take care with flat cable, which might be pushing connector to side. If so - I found easy to put connector in place before tightening screws on step 23 and 22. Because then logic board can move a bit when repositioning connector and to slide right place before connecting it properly.

Note that there is a rubber insulator that is loosely attached to the PBC that can be seen in the upper right corner of the red outline near the tag with Q5M on it. It falls off after the logic board is removed and should be replaced before reassembly.

As noted: Put the bumper back right above the white bar code label. The label says Q5M on the far right side. The bumper goes on the edge of the board to protect the ribbon cables that bend over the board.

So, I couldn't gind the tape and instead of digging around. I did what no one should do. I twisted and pulled. So now the screw that holds the upper left corner on broke that part of the logic board off. Everything else went back great....Phone won't turn on. Am I screwed here?

Under the screw is a ground clip from step 25. I tweezed it out here since it might bounce free while pulling logic board out. Use a big white towel as a work surface to prevent wayward bouncing bits from flying off the table.

If your driver is just spinning in this step, you may be trying to turn the offset screw instead of the phillips screw beneath the tape. The tape is not obvious, and I found tweezers helpful when removing it.

The Kit Provided flat head screw driver didn't fit in the stand off screw heads on my IPhone 4s. I had to use it in only one side of the screw notch to slowly twist them out. Its doable but could use a larger flat head, but the blade needs to be micro thin.

I wound up stripping one of the screws on this step. Was frustrating but I found if I too a sharp knife and gently went back n forth I was able to make a little notch to use a flat head and got it off. Other than that all went well.

After I had lifted the logic board and moved around a little a small rubber piece fell off. Approx. 1 cm long and 2 mm wide. I'm guessing it's for some sort of isolation between the board and the chassis. Where should it go when I reassemble the phone?

It sits between the logic board top-edge and the two ribbon leads from the screen. Its purpose is to stop the PCB cutting in to the FPC leads over time due to vibrations. If you require I can send a photo.

On reassembly, make sure you lift up the power button cable before installing circuit board. I thought I had all of the cables lifted until after getting to step 17 (in reverse) only to find out power cable was under the circuit board. Added 15 minutes to my process.

I had a similar problem as I was back tracking steps to perform something I missed and actually broken the power and sensor cable (the one that is connected to the digital board first during re-installation. A secondary order and another 20 minutes took care of it. Glad you were able to not hit that barrier.

On reassembly, you are putting the plate under the spaghetti. I went back a few times to get all the cables out. Here is a check list before you tighten any logic board screws or try to jam the top edge of the board in place:

Counter clockwise from upper right near power button:

- Wi-Fi Cable from step 21

- 5 cables near the camera from step 17.The ‘blue’ power cable underneath loves to hide. The ‘orange’ front facing camera cable can get kinked under the board during re-install (no more selfies on this phone).

Before logic board re assembly it is nice to use scotch tape ( temporarily) to bend all the connections above the battery compartment . Doing as such avoid to have the power button connection remaining below the logic board .

Hi. This little clip is responsible for the image stabilization on the 4S. When the iPhone 4S was launched, one of the things that were different from iPhone 4 was Image Stabilization, specially when the user was filming. This clip holds the camera module in place while the phone is shaking in the hands of the user. Pretty high tech :D

I used a Tupperware orange peeler as a plastic opening tool and didn't touched any screws oder other inner parts.

I had to do it two times, because my old 4S 64GB has a broken WLAN Chip on the logic board, and my wifes 4S has broken her display glass. So I took her logic board into my 4S body. Now we have one running iPhone 4S 64GB instead of two broken phones.

Step 26 cause me great pain as well. I couldn't get it loose with the plastic spudgers. I had to break out a tiny metal screwdriver. I was so paranoid that I was going to break the part or the clip. The trick is to get under the clip's "fingers" that fasten it on the sides. The issue is that even my small my plastic spudger was too big to fit in the available space. Ultimately I got it to work with a micro flathead screwdriver, but it wasn't without serious concern.

Yes, this is hard. It would be a lot easier if the guide had a picture of the retainer clip. I was successful with a spludger by lifting it on the upper left hand corner. Once you have it off, have a good look at it before putting it back on. Remember that it clips to the outside of the camera housing.

it is unnecessary to remove this plate or the front camera. its very difficult to remove and very difficult to replace. totally unnecessary step. just be careful moving the flex cables around, that's the only thing that is in the way, the camera does not hinder the power/sensor cable.

fyi my comment is based off replacing the power cable not the front camera, apparently the guides are just copied off one another. again, this is one of the hardest things ive done on an iPhone. if you are fixing the power cable, DO NOT pull out the front camera, NOT NEEDED and VERY HARD. im currently still trying to re-install the cover plate.

YES, DO NOT TAKE THIS PART OFF. The reason the guide says to take it off is because in step 30, it might get in the way. If you be a little more careful, the cable coming from the camera won't be a problem. However, if you do take the retainer and the camera off, you should expect your repair to last a couple more hours. I have spent several hours on some repairs trying to put the retainer back on, and then realized that it was 90% useless to do so.

I totally agree with Andrew, when changing the power and sensor cable, do not do this step. It is absolutely unnecessary and only increases the pain when reassembling your phone. That step should not be in the guide for the power cable replacement.

Based on comments here, I skipped this step fixing the power button and it was fine, you have a little less room to remove the earpiece wrapped in the power cable but if the removal was as hard as people describe, it was easily worth it.

I could not reassemble the retainer. The legs would not go back to where they were meant to go and I badly bent one in the process. I replaced the retainer with a small dop of Blu-Tack ("a reusable putty-like pressure-sensitive adhesive"). This gets squashed down when you replace the logic board. This keeps the camera correctly positioned and works OK so far.

If youare changed the earpiece you can skip step 26 till 31. got to step 32 and remove the black clip without disassembly the earpiece assembly and then tear of the speaker. follow the steps of the crazyphones on youtube guide.

I think the key to getting this clip on is knowing that the fingers do not clip on the inside of the retainer, but slide over the top and the 'elbow' locks in the retainer openings. This makes it a ton easier.

There is no need to remove the front facing camera or power button/flex. At this point you can just remove the retainer clip over the sensor assembly, pry the sensor assembly from it's holder, bring it back over and clear of the earpiece speaker, carefully pry the speaker from the frame, replace the speaker with new one, reassemble.

Getting this off with a micro flat head is best - putting it back on you need to slightly flare out the little fingers on the side two (facing top and bottom of phone-just enough to make getting it back on easie. Then using ifixit flat tweezers you can get in and pinch the fingers closed again once it's on.

I quickly regretted not having read the comments to this step and the next one. When replacing the power/sensor cable, this step isn’t necessary, provided you are careful enough with the earpiece speaker and the sensors which are next to the front facing camera.

DO NOT DO THIS unless you are sure you have to. This step and the next one are not necessary when replacing the power and sensor cable.

It is very very difficult to fix the front camera retainer again after removing it.

When I took out the old headphone jack assembly the secondary mic was still attached to the housing because there was so much adhesive on it. be very careful when taking the old unit off so as not to remove the adhesive part unless you have more of it.

As the other comments say, you have to be very careful about removing the secondary (top) mic at the same time as the headphone jack. The secondary mic is tethered very tight to the jack with a flex at the very top of the phone housing, and it is easy to break this connection. This is important to pay attention to if you are following this guide in an attempt to move the headphone jack out of the way for another repair.

The part is very small but if you are replacing the headphone jack, the mic is part of it. It it's important to know the position of of how the ribbon cable is bent. I used tweezers to pry the mic from the mic box but an exacto blade would had done a cleaner job. I got a good pic but at the time of this comment I was into fixing the phone. ;'D

There should be a warning in this step. The mic is actually a part of the headphones jack. it is not mentioned in the guide, and when you're pulling out the jack you're ripping off the mic ribbon that sits below the jack.

Here's another one who tore off the secondary mic. :/ I came here to pop out the headphone jack so I could replace that corner 1.5 mm Philips, in the process of a screen replacement. So now I have another job! I don't mind since it was my own f-up, but I'll add a comment on the other process in order to draw attention to the secondary mic being easy to tear off.

Another problem: strangely, the headphone jack won't fit back in. I'm fearful of pressing too hard, in case something else gets messed up - but in preparation for replacing it, I wanted to practice getting the jack in.

I think the tiny metal part of the frame (with a small circle in it, visible right above the headphone outlet in step 31) is bent, somehow. Any advice for me?? I would appreciate it!

I found that it helped to have the silent switch off (closer to the front cover) than on for reassembly with a new headphone jack. Little tip but it can save a bit of frustration trying to line up the outer switch cover and inner switch mechanism.

The adhesive on the replacement part is far inferior to the original. The cable around the the audio jack and the mic should have adhesive, as the original part does, but it is missing. This makes the reassembly tricky because you need to check that the headphone cable is out of the way when installing the front facing camera and the main logic board. The mic needs adhesive, but none is provided. I used a little superglue will hold the mic in place. Use just enough to hold the mic in place. Once the logic board and grounding clip are installed, the mic will be wedged in place.

My repair was successful, but this replacement part was well below iFixit's normally high standard of quality.

Putting a new one of these switches in seems to be quite difficult because I've had 3 separate issues, and friends have had similar troubles. when you put the switch back into the bracket it should be in the 'up'(silent) position, don't use glue, in fact I even remove the sticky tape apple put in there, the bracket will keep you from pushing the switch in. Just make sure the two little black peg on the bottom side of the switch aren't broken, they hold the switch in place. And don't push too hard on it, it seems to be fairly delicate, either that or it just has a high failure rate.

Make sure you test your silent switch right off after booting your device back up.

Be very careful with this step. Putting the new switch back correctly is very hard and is made more difficult because the replacement switch is not identical to the Apple original. The Apple switch has two short pegs, almost nubs, on the back of the switch that help anchor it in the bracket, which has two holes to match the pegs. The replacement switch has much longer pegs, which maybe the manufacturer thought would be an improvement, but it is not. If you don't get everything aligned well, then the torque on these longer pegs can easily shear the pegs off entirely. If this happens to you, note that a careful application of superglue will secure the switch to the bracket (don't get any in the switch). After this problem I found it easier to install the bracket and then affix the switch to the bracket, making sure that the finger of the switch was correctly fitted into the slider button.

I've done this replacement 5 times now and still cannot get the volume buttons to work properly after metal bracket has been moved to the new flex cable. Each time I reassemble the phone, I have to almost completely back out the volume button bracket screws in order to allow the volume buttons enough movement to operate the buttons on the flex cable. Even then, the volume buttons do not feel right (though they at least appear to work)

Is there any trick to getting the volume button/flex cable/bracket mounted back to the frame so the volume buttons will "click" properly again?

switch has two short pegs, The replacement switch has much longer pegs,

"

The "longer" pegs become "shorter" pegs when properly melted to shape. Apple's have already been assembled, your new part is awaiting assembly. The posts are inserted into the bracket, and the pegs are melted down into the bracket. Take a large paperclip and heat it up with fire, and using the glowing hot end of the flat end, gingerly touch the top of the protruding pegs. they will melt down and fill the cups on top of the mute switch bracket, holding the switch firmly in place. Make use to use slight vertical pressure with the switch itself firmly held by tweezers or something, so the bracket is flush against the switch. You can also cut off the protruding ends of the posts, and put a very small amount of super glue int he cups to hold the posts. keep the glue away from the switch side, but with the way the switch is designed, this puts a lot of twisting stress on the switch, which the melted ends were designed to take.

The instructions failed to mention that the vibrate switch alignment pins are actually plastic rivets and MUST be melted into the bracket for proper adhesion into it's fixed position. This prevents switch from backing out of bracket, and will insure proper operation of switch.

This information would have saved me, a first timer, over an hour of research. Also in my first time around I thought the pins should be pressed flush and I proceeded to press them without heat. The thinner pin pushed into the switch rendering it useless! I realize this helped you sell me the part a second time but don't think that's cool... Eduardo Benarroch, Weston, Fl.

So I am going to safely assume that this has to be one of the hardest if not the hardest of the repairs to actually complete... I've done this twice now... successfully once (the most recent thank god). I had completed this once before but the part I bought from this asian store in Toronto had given me the part with no little black peg on the vibrate switch, ergo the vibrate switch didnt work for me for the longest time... now... I received the product from this site, which was perfect! Still an incredibly hard and frustrating experience, but that has to do with what you actually have to do and nothing to do with the guide. The guide is simple and excellent in all aspects. Thanks for saving a student even more debt :)

I completed the process and everything seemed to go well however once I turned on my phone it now thinks that many headphones are always plugged in. There isn't anything stuck in the headphone jack because it is brand new, so does anyone have any ideas ?

My replacement lcd came with a lot of these pieces tucked away, nice+neat, already in place along the inside edges of the 'mid-frame, silver colored section that attaches to the inside of the LCD. I was following along with the instructions, trying to be careful and not damage any of the ribbon cables or tear out a soldered connection etc. I hadn't even taken my lcd from its bubble wrap.

When I finally think to open it up and check it out. Turns out I could have stopped after taking out the speakers. My new LCD had a home button already installed. And what looks like everything in the upper section, except for the camera, was included, 'pre-installed on my LCD. Looks like I have a wide ribbon cable coming from under a speaker to get.

And at a glance, the Dock connector section looks like it might be the lastand then the dock connector looks like its the last of the bits+pieces that need 2 be moved over 2 the new phone. But I'm not sure what 2 take off first, and what's considered2 be a part of the dock.
